We examine why companies in South Africa voluntarily provide a value added statement (VAS). The VAS can be used by management to communicate with employees and thereby establish a record of legitimacy. Since we want to establish if the VAS is used to establish symbolic or substantive legitimacy, we examine whether production of a VAS is associated with actual performance in labour‐related areas. To measure labour‐related performance, we use an independent Black Economic Empowerment (BEE) rating. We find that BEE performance is significantly and positively related to the voluntary publication of a VAS. Our results suggest that BEE performance and disclosure of a VAS are two elements of a strategy used by South African companies to establish their substantive legitimacy with labour.  相似文献

Social marketing involves influencing voluntary behaviour of people towards a social end. Examples of social marketing range from campaigns to encourage healthy physical behaviour to efforts to encourage tax support for public education, overcome racism, or stimulate ‘patriotic’ behaviour. Using data from a summer 2001 telephone survey of 600 young adults, this paper investigates how recruitment campaigns may benefit from considering gender differences in importance ratings of a variety of benefits promoted by the military in the USA. Importance ratings are assessed using differences in means and variances tests. Findings identify gender specific differences that may be used to enhance recruitment campaigns.

We examine the costs and benefits of the global integrationof initial public offering (IPO) markets associated with thediffusion of U.S. underwriting methods in the 1990s. Bookbuildingis becoming increasingly popular outside the United States andtypically costs twice as much as a fixed-price offer. However,on its own, bookbuilding only leads to lower underpricing whenconducted by U.S. banks and/or targeted at U.S. investors. Formost issuers, the gains associated with lower underpricing outweighedthe additional costs associated with hiring U.S. banks or marketingin the United States. This suggests a quality/price trade-offcontrasting with the findings of Chen and Ritter, particularlysince non-U.S. issuers raising US$20 million–US$80 millionalso typically pay a 7% spread when U.S. banks and investorsare involved.  相似文献

The paper asks the question – as time series analysis moves from consideration of conditional mean values and variances to unconditional distributions, do some of the familiar concepts devised for the first two moments continue to be helpful in the more general area? Most seem to generalize fairly easy, such as the concepts of breaks, seasonality, trends and regime switching. Forecasting is more difficult, as forecasts become distributions, as do forecast errors. Persistence can be defined and also common factors by using the idea of a copula. Aggregation is more difficult but causality and controllability can be defined. The study of the time series of quantiles becomes more relevant.  相似文献

Two of the main forces driving European emigration in the late nineteenth century were real wage gaps between sending and receiving regions and demographic booms in the low‐wage sending regions. Our new estimates of net migration for the countries of sub‐Saharan Africa show that exactly the same forces driving African across‐border migration are at work today. The results suggest that rapid growth in the cohort of potential young emigrants, population pressure on the resource base, and slow economic growth are likely to intensify the pressure for migration out of Africa and into high‐wage OECD countries over the next two decades.  相似文献

We examine voting by a board designed to mitigate conflicts of interest between privately informed insiders and owners. Our model demonstrates that, as argued by researchers and the business press, boards with a majority of trustworthy but uninformed “watchdogs” can implement institutionally preferred policies. Our laboratory experiments strongly support this conclusion. Our model also highlights the necessity of penalties on insiders when there is dissension among board members. However, penalties for dissent appeared to have little impact on the experimental outcomes.  相似文献
